Abstract In view ofHammond's warning6 about the “Conspiracy of errors”, found in the case of low values of equilibrium constants of charge-transfer complexes a case is made out for redetermining the values for the system hexamethylbenzene—2,3-dichloro-1,4-naphthoquinone. Uncertainties in the parameters were estimated using theLiptay 8 matrix procedure. The solvent used was dichloromethane. The following data were obtained at 25°C: vC T = 22,220 cm−1;E A=0.99 eV;K ɛ=2599±57 l2·cm−1·mol−2. ɛmax= 1020 ± 148 cm−1··1;K=2.55±0.37 l·mol−1; −ΔH=2.7±0.3 kcal·mol−1.
